Brief Summary:

Following arthroscopic shoulder surgery a small but significant number of people suffer severe postoperative pain.

This study aims to predict which patients are at risk of developing severe post operative pain so that they may be targeted with a more aggressive post operative pain regimen.

Condition or disease Intervention/treatment Phase
Arthroscopic Shoulder Surgery Pain Threshold Device: Electrical pain threshold measurement Device: Measurement of electrical pain threshold Not Applicable

Detailed Description:
Patients presenting for elective (day case) arthroscopic shoulder surgery for either Arthroscopic Subacromial Decompression (ASD Group) or Rotator Cuff Repair (RCR Group) are recruited. Using a Cefar PainMatcher, a pain and sensory threshold assessment tool, consenting patients will have their preoperative pain thresholds recorded. The patients will then have a standard anaesthetic administered with TIVA (propofol/remifentanil) and either a subacromial injection (ASD Group) or interscalene block (RCR Group). Four days following surgery a telephone questionnaire will be completed by the patients recording their worst pain score since surgery.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 43 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Screening
Study Start Date : March 2009
Actual Primary Completion Date : May 2011
Actual Study Completion Date : May 2011

Arm Intervention/treatment
Experimental: Electrical pain threshold measrement patients Device: Electrical pain threshold measurement
Assessment of preoperative pain threshold using electrical stimulation using a Painmatcher machine.
Other Name: Pain Matcher ® (Cefar Medical AB, Lund, Sweden)

Device: Measurement of electrical pain threshold
Measurement of preoperative electrical pain threshold and self reporting of postoperative pain scores (for 4 days) on VAS.
Other Name: Pain Matcher ® (Cefar Medical AB, Lund, Sweden)

Primary Outcome Measures :
  1. Post operative pain level [ Time Frame: 4 days ]
    Post operative pain level recorded on a VAS (0-10) at rest and movement for the first four days pots shoulder surgery. This information will be correlated with the preoperative pain threshold of patients taken with the Pain matcher machine.
